The Accurate Total Equilibrium Equation and Tangent Stiffness Matrix of Three Dimensional Lattice Elements
【摘要】 利用Green应变张量在随动坐标系中建立一维桁架单元的精确全量平衡方程,然后将其转化成固定空间坐标系中的全量平衡方程,并由此导出精确的切线刚度。
【Abstract】 In the paper,the accurate total equilibrium equation of one dimensional lattice element in the coordinate has been given by using Green Strain Tensor,then it is changed into one in the fixed three dimensional coordinate,so we can get the accurate tangent stiffness matrix.
